# Replicate

> Run and deploy any open ML model — LLMs, image, video, audio — through one API with pay-per-second billing, and package your own with open-source Cog.

Replicate is a hosted platform for running open machine-learning models — LLMs, image, video, audio, and more — behind a single API, billed per second of compute with scale-to-zero when idle. Thousands of community models run with one line of code, and you can package and deploy your own using Cog, its open-source container tool. Replicate joined Cloudflare in 2025.

Replicate is a hosted platform for **running and deploying open machine-learning models through an API**. Instead of provisioning GPUs, building containers, and writing inference servers, you call a model — Stable Diffusion-style image generators, video and audio models, open LLMs, and thousands of other community-contributed models — with a single line of code and get results back. The platform handles the GPUs, scaling, and queuing.

Its defining design choice is **pay-per-second compute with scale-to-zero**: you are billed for the time your code actually runs and nothing while a model sits idle, which makes it well suited to spiky, experiment-heavy, or low-volume workloads where a dedicated endpoint would mostly burn money. Some models are billed per output (per image, for example) rather than per second. New accounts can try a curated collection of models free for a limited number of runs before moving to prepaid credit.

The bring-your-own-model path runs through **Cog**, Replicate's open-source (Apache-2.0) container tool. You describe a model's environment and inputs in a single config file, and Cog produces a reproducible container with an HTTP inference API and CUDA/dependency setup handled for you — then you push it to Replicate to get an autoscaling endpoint, identical in shape to the community models. Against infrastructure platforms like [Modal](/tools/modal) and Baseten, Replicate leans hardest on breadth of ready-to-run open models and the one-line API, where the others center custom code and deployment control.

Replicate **joined Cloudflare in 2025** (announced November 2025); the product continues to operate under its own brand. For weighing a hosted inference API against running models yourself, see [self-host vs. API LLM](/guides/mlops/self-host-vs-api-llm).
